Cultivation of the Students’ Critical Thinking Ability in Numerical Control Machining Course Based on the Virtual Simulation System Teaching Method

The critical thinking ability is the premise and foundation of innovation ability. It is also an important goal of talents training in higher education. College English teaching should not only focus on the cultivation of students’ English knowledge and skills, but also the cultivation of students' critical thinking ability. This article first discusses the connotation of critical thinking ability, followed by theoretical foundation introduction and analysis of the problems of critical thinking cultivation of English majors, and finally puts forward the countermeasures of cultivating students' critical thinking from the following eight aspects: paying attention to classroom questioning skills, changing the classroom teaching mode, creating relaxing teaching atmosphere, building a new student evaluation system, designing the classroom teaching reasonably and improving teachers' critical thinking ability and raising students' awareness of critical thinking ability self training, adopting PBL teaching method, in order to effectively cultivate students' independent thinking and judgment ability, and to better improve the teaching effect of college English.

AbstractThe purpose of this research were to examine the effect of contextual learningmodel of Relating, Experiencing, Applying, Cooperating, and Transferring (REACT)with Virtual Simulation to critical thinking ability and student learning activity inSenior High School. The type of this research was experimental research using posttest only control group design. Population in this research was the tenth gradestudents of SMAN 2 Jember. The data were collected by observation, documentation,interview and test. The data were analyzed using Independent Sample T-Test withSPSS 24. The results showed that the average value of critical thinking ability ofexperimental class was 81,15 and control class was 69,91. In result of activity valueof experiment class was 86,943 and control class was 79,934. This study can beconcluded REACT learning model with virtual simulation have an effect onsignificance to critical thinking ability and student activity in physics learning insenior high school.Keywords: Contextual learning model of REACT, virtual simulation, criticalthinking, student learning activity

Penelitian ini dilakukan untuk mengetahui peningkatan kemampuan berpikir kritis siswa pada mata pelajaran Termokimia melalui penerapan strategi Process Oriented Guided Inquiry Learning (POGIL) (POGIL) di kelas 11 SMAN 8 Pekanbaru. Penelitian ini menggunakan One Group Pretest-Posttest Design yang diadakan di SMAN 8 Pekanbaru pada tahun akademik 2017/2018. Objek penelitian adalah XI MIA 1 yang terdiri dari 32 siswa. Pengumpulan data siswa menggunakan teknik tes pretest dan posttest. Keberhasilan pembelajaran dalam meningkatkan kemampuan berpikir kritis siswa ditunjukkan oleh peningkatan kriteria berpikir kritis dari hasil pretest dan posttest yang menganalisis persentase skor berpikir kritis. Hasil penelitian menunjukkan bahwa ada peningkatan kemampuan berpikir kritis siswa. Siswa mengalami peningkatan dari kategori berpikir kritis sangat rendah ke kategori sangat tinggi dengan persentase 15,625%, dari kategori rendah ke kategori sangat tinggi adalah 40,625%, dari kategori rata-rata ke kategori sangat tinggi adalah 9,375%, dari kategori sangat rendah hingga kategori tinggi adalah 12,5%, dan dari kategori rendah ke kategori tinggi adalah 21,875%. Berdasarkan analisis data, dapat disimpulkan bahwa penerapan strategi Process Oriented Guided Inquiry Learning (POGIL) mampu meningkatkan kemampuan berpikir kritis siswa pada mata pelajaran Termokimia di SMAN 8 Pekanbaru. The research was held to determine the improvement of student’s critical thinking ability on Thermochemistry subject through implementation of Process Oriented Guided Inquiry Learning (POGIL) strategy at 11th Grade of SMAN 8 Pekanbaru. This research used One Group Pretest-Posttest Design which held in SMAN 8 Pekanbaru at academic year of 2017/2018. The object of research is XI MIA 1 that consist of 32 students. The data collection of students used test technique which are pretest and posttest. The success of learning in improvement of student’s critical thinking ability is showed by improvement of criteria of critical thinking from pretest and posttest results that analyzed the score percentage of critical thinking. The result of research showed that there was an improvement of student’s critical thinking ability. The students have an increase from the very low category of critical thinking to very high category with percentage of 15,625%, from low category to very high category is 40,625%, from average category to very high category is 9,375%, from very low category to high category is 12,5%, and from low category to high category is 21,875%. Based on data analyze, it can be concluded that implementation of Process Oriented Guided Inquiry Learning (POGIL) strategy is able to improve student’s critical thinking ability on Thermochemistry subject at SMAN 8 Pekanbaru.

Mathematical Critical thinking is one of mathematical abilities that must be obtained by students. Critical thinking is one of the high order thinking processes that can make concepts in student knowledge. Students with critical thinking in mathematics learning mostly do rational activities such as interpreting information based on a particular theoretical framework, linking theory with practice, making claims and justifying it, utilizing data in support of argumentation, making relations or relationships between various ideas, asking questions, evaluating knowledge, predict, describe something, analyze, synthesize, and categorize. This study aims to analyze the effect of the Concept-Based Learning Model on the critical thingking mathematical abilities.The purpose of this research is to analyze the effect of Concept-Based Learning Model toward mathematics critical thinking ability. The method used in this research is quasi experiment by Randomize Control Group Post Test Only Design with cluster random sampling technique. Indicators of mathematics critical thinking skills measured in this study include providing simple explanations, building basic skills, concluding, making more explanations, and deciding an action. The results showed that the mathematics critical thinking ability of students in the experimental class for the five indicators that being analyze was higher than the ability of students in the control class. A fairly high difference in the indicator showed in give a simple explanation and concluding. and it means that the application of Concept-Based Learning Model significantly influences the abilities of students' mathematics critical thinking.

This research is conducted by the low mathematics critical thinking ability of students in junior high schools, especially in VII grade .Students of VII grade commonly are transitioning from elementary school to junior high school could be a reason how low students of VII grade on mathematic critical thingking ability. The low ability mathematics critical thingking one of caused by mathematics anxiety. This study aims to find a relationship between math anxiety and mathematics critical thinking ability of VII grade at SMPN 5 Serang City. The method of this research is quantitative descriptive by making 110 students from VII grade as a sample. The data were collected using questionnaire and test. The result of this study indicate that 1) the ammount of correlation between math anxiety with critical thingking ability is -0,5991> rs table 0,1695, which means there is a significant and negative relationship between anxiety and critical thingking ability 2) the average of students’s mathematics critical thingking ability is different where score between students with low anxiety have a better score than student with mid anxiety and low anxiety,and students with mid anxiety have a better score than students with high anxiety, and students with mid anxiety have a better score than students with high anxiety.
